Title: Method for removing foreign matter stuck on surface of glass
Inventor: UEDA MASAHIRO
IPC: A47L1/00
Filed: 1991-07-09
Abstract: PURPOSE:To enable foreign matter stuck on the surface of glass to be removed from the inside of a room in a simple manner by the use of a non-contact means from the opposite surface side of glass by irradiating the laser beam of ultra violet rays having specified energy density. CONSTITUTION:The laser beam of ultra violet rays which is 100 [ns] or less in pulse width, and is 0.1[J/cm<2>] or less in energy density, is irradiated onto foreign matter stuck on the surface of glass while the surface of glass is being penetrated through. In this case, since the laser beam is small in pulse width, both energies for instantly heating and evaporating the matter while being scattered, are imparted to the foreign matter. This constitution thereby enables the foreign matter to be completely removed while they are being evaporated and scattered with no surface of glass impaired (on which the foreign matter is stuck), allows the secondary equipment of a lifting device grounded to the roof top to be eliminated, and also allows works to be processed from the inside of a room.
